John, I don't know which climate is in OH, but what I can say on Lilium candidum is that this is a true Mediterranean species, that is, winter growing and needs an hot summer rest. Although originates in Middle East and Greece, it is cultivated since the Roman Age and I read it was even know by the Egyptians. It needs an alkaline soil, well drained and LOW in organic matter ( a shallow stony one is perfect), otherwise it will rot easily. It is also sensitive to transplant and takes time to restablish, as the fleshy roots are perennial. It doesn't develope roots from the base of the stalks, unlike many other lilies. I split my clumps every 4-5 years, when they become too crowded and replant immediately. Bulbs are put just at level soil, but I leave their dried leaves on, as mulching, to protect them from excessive sun. In autumn, after the basal whorl of leaves have developed, I spread around a bit of superphosphate. I don't give them either a drop of water and they grow with natural rains only. It was used here as crop for cut flower many years ago, but nowadays it has been replaced from many oriental hybrid and longiflorum, because these can be forced to flower all year around.
